2019: The Year of The 5MR

In 2018, White-throated Sparrow was a county bird, a Five Mile Radius bird, and eventually a yard bird! This was the #1 bird I was hoping to see at Rancho de Bastardos that I kind of expected to show up eventually, and this looker spent a few days here right before Christmas. Sadly, it abandoned us before 2019. Another fun fact: every White-throated Sparrow I've seen in my home county has been in my radius! I would grade my radius as being middling for sparrows, maybe even above average. Fingers crossed for a Harris's this year, though it would not have to show up in my yard to make me happy. 

By this point, every regular BB&B reader has heard about the Five Mile Radius (5MR) and has one of three opinions on it.

Opinion A: 5MR is a fantastic idea and I'm already doing one!

Opinion B: 5MR does sound interesting but not interesting enough for me to start one...yet.

Opinion C: 5MR is stupid. It is stupid because listing is stupid/I am too invested in rabid county listing all over the state/I am busy because I am always doing a big year and need to spend hella time driving or flying/not everyone is doing it so therefore I will not do it/I suck.

If you are of Opinions A or B, or even the highly unlikely Opinion D ("What is 5MR?"), then this post is for you. If you are of Opinion C, well, god help you.

My 5MR is very good for sapsuckers; I saw Red-breasted (above, fairly common here), Red-naped and Yellow-bellied all in 2018. 2019 started with Red-naped (a different one) and Yellow-bellied...nope, no Red-breasted yet! If a Williamson's ever shows up it will probably be in a little park or cemetery no one birds, and 5MR is all about birding places like that. Photographed at Almaden Lake County Park.

I am not going to punish regular readers with describing what 5MR is all over again, but in case you are wondering what all the fuss is about, you can read this BB&B post and check out Flycatcher Jen's new handy little 5MR FAQ page.

BB&B is world-renowned for being a leading trendsetter, influencer, and tastemaker for birding in the 21st century, but Flycatcher Jen, PNW's blogging darling, gets full credit for launching this concept...we are just here to preach the radial gospel. I am a 5MR missionary, if you will, and in the end many of you will be converted, or in other words, saved. The birding paradigm is beginning to shift. So what is new with 5MR birding?

Last fall was excellent for Willow Flycatchers in Santa Clara County; this one was in my yard for a few days in September. There are a number of decent places in my 5MR to check for migrant Empids, but kingbirds are much tougher.

The 2019 5MR challenge is what is new. Jen has invited birders everywhere to come join in; she is tracking everyone's 5MR for 2019, and is at almost 150 (!!!) participants in many states and multiple countries! It's really all about birding your 5MR (or 8.05KR if you are metrically inclined) a lot this year, and we will be tracking many more metrics than just the usual who-will-get-the-most-species stat. She is even doing monthly challenges! You can read all about it right here, and if that grabs ya check out some more of the nerdy, jaw-clenching metrics right here. She also set up a Facebook group devoted to 5MR, which is (somewhat unexpectedly) really flourishing - go here to check it out and join up. No need to sign up for the 2019 challenge to be in the group!

Birders of all levels and all stripes have embraced the 5MR, and you should too! Bird Police, civilian bird wizards, "young birders", geri birders, intermediate birders, and probably some stringy ones...we are all here! Come revel in the places less birded and the luxury of never having to drive more than 20 minutes from your home! Become the master of your local eBird hotspots, or if there aren't many, you can bring them into existence yourself! Of course, there is no need to sign up for the 2019 challenge to enjoy the fruits of 5MR, but I think it will be fun.

Easily one of the best birds in my 5MR last year was this Blackburnian Warbler, which I dipped on twice before connecting. I'm still figuring out how readily findable fall vague runts are in my 5MR, but clearly searching for them is not a fruitless endeavor. Incredibly, in December I got to see another one only 0.3 mile outside my radius. Photographed at Vasona Lake County Park.

Those of us living in urban areas tend to be very heavily biased towards months with wintering birds and lots of migrants passing through, but obviously no matter where you are, you can't forget about the birds that breed in your 5MR! Much of my radius is urban/suburban hell, but a lot of it is protected open space as well, mostly in the form of oak woodland, modest riparian corridors, and some chaparral. Good summer birds in my 5MR include Black-chinned Hummingbird, Vaux's Swift, Common Poorwill, Rufous-crowned Sparrow and Band-tailed Pigeons. I'm sure the pigeons are here year round but I don't see them around where I live for most of fall and winter. Look at this ridiculous thing mantling my tiny feeder! Need to track down Western Screech-Owl in my radius this year, among other residents/breeders.

I've said this a number of times now but there are a huge number of gulls in my radius in the winter months. I really, really want to find something rare in my 5MR (probably Glaucous, Lesser Black-backed or Slaty-backed) and in fact I'm sure they are around, it's just a matter of being in the right place at the right time. This Iceland was casually soaring over my yard last month.

If gulls and waterbirds are strengths, and perhaps even upland birds, the Achilles Heel of my 5MR is shorebirds. Why do they have to be so hard? Every species of shorebird I have recorded in my 5MR has been from my yard. That would be one species of plover (Killdeer, claro) and 4 sandpipers, of which Wilson's Snipe is the only interesting one, though it is the only expected one besides Spotted. It's pretty bad but I will take my snipes. Solitary is possible but I can't even fathom seeing something like a flock of peeps.

Not only do I have all three mergansers in my radius, I've seen them all from my yard! Red-breasted was a fluke though and I'm not sure if I will get another one in the radius this year. The ponds at Los Gatos Creek County Park are very reliable for Hooded Mergansers (where these cripplers were hanging out), which is probably the most heavily birded hotspot (for good reason) within my 5MR.

In 2018, I fared somewhat better than I thought I would in my 5MR. Birding at the very edge of my 5MR at Santa Teresa County Park in spring gave me some great birds like Calliope Hummingbird, Horned Lark, Grasshopper Sparrow and Rock Wren. The radius is real tricky there, with some sections of trail inside and some outside, but I finally got a good handle on it. Fall migration bestowed upon me a nice array of new 5MR birds like Cinnamon and Blue-winged Teal, Greater Scaup, Palm Warbler and Brewer's Sparrow. A Summer Tanager showed up right before Christmas, and the nearby Phainopepla is wintering at the same site again. I finished the year with 159 species in my 5MR without being really committed to inflating that total, which I'm pretty happy about - a few other 5MRs in Santa Clara County finished slightly below that number, though I have no doubt someone living closer to the salt ponds could do better than me, probably substantially so.

My 5MR has most of the expected Northern California wading species, though White-faced Ibis is not something that will be easy to find. Perhaps a Yellow-crowned Night Heron will turn up behind my house with all the Black-crowneds at some point? Yellow-crowned is long overdue in this part of the state and they have been increasing in Southern California. Until then, I will be content with the expected locals, like Great Blue Herons, when they choose to be confiding. Photographed at Los Gatos Creek County Park.

Of course, just because you don't want to sign up for the 2019 challenge doesn't mean you shouldn't do a 5MR at all! Absolutely none of my 5MR birding last year, or the year before, was done with me thinking about getting freaking year birds for my 5MR list...how embarrassing is that? It's pretty embarrassing...but oh wait I am ALL IN on the 2019 challenge so this year will be different!

Well, maybe not all in...I am about to leave for Belize. So long White-crowned Sparrows, hello Tody Motmots! See you on the other side Bushtit, pleasant good morning to you American Pygmy Kingfisher! Godspeed Hutton's Vireo, oh so good to finally meet you Yucatan Vireo!

Right, but otherwise I am heavily invested. Looking forward to checking out some new spots (a couple cemeteries immediately come to mind), tracking down a few self-found rarities, and really pinning down species that I have yet to see in my 5MR that I could reasonably expect to find here...Eared Grebe, Allen's Hummingbird, Red-breasted Nuthatch, and Tricolored Blackbird all come to mind quickly, though that does not mean they will come easily. I am hoping to see some more 5MRs pop up in Santa Clara County in 2019 as well!

Challenge or no challenge, hope you all have a very radial 2019!

My last Santa Clara County bird of 2018 was also my last new 5MR bird. American Bittern was the closest thing I had to a nemesis bird in Santa Clara. Ugh I love bitterns so much, happy that they are possible in my radius. Photographed at Los Gatos Creek County Park.

Blazing a Fiery Trail of County Birds

As the sun sets on this Short-eared Owl (COUNTY BIRD!), so too does it set on another summer of relative birding slumber. For the rest of the year, the birding in Santa Clara should be quite good, and I hope to see more pleasant county birds like this one. Photographed at Coyote Valley Open Space Preserve.

September. Sweet, sweet September, how I've missed you. BB&B sings the praises of September each and ever year, and as long as my heart beats and about half my brain works, I will continue to do so. September just doesn't get old. In just a few short weeks, the state of local birding has gone from the hot, grim dirge of summer to that special time of year where anything can happen. September is gripping. We are no longer looking at a dim and distant light at the end of the tunnel, we are basking in the light of full bore fall migration. That holds true even here in humble Santa Clara County, where finding eastern-flavored rarities is a back-breaking (but not impossible!) task compared to the coastal counties.

I think I've said it before, but when I first moved to San Jose my main coping mechanism to unexpectedly find myself living here was getting really into birding Santa Clara County. Not obsessively, but semi-devotedly. Now, about 16 months in, I feel like I have a grasp of birding here. I know what my easiest needs are without consulting eBird, I have an inkling of where to be looking for what, and I'm very interested in checking out all the birding sites I haven't been able to visit yet.

Here are a few observations I've made about the birding here in general:

*There are lots of birders here, but not many regional or state rarities. Yup, there you have it. Since moving here, the only review bird I've seen was Will Brooks' Little Stint in August of 2017...that is over a year ago. The only other review species seen here since then that I am recalling was a Slaty-backed Gull in March, which I dipped on. Where are the vagues?

*Well I know where some of them are...they are probably flying right over my house. There are huge numbers of gulls in the county in winter, and thousands (mainly Herring, California, Glaucous-winged and Iceland) may go right over Rancho de Bastardos on some days. I suspect Slaty-backed Gull may actually be an annual bird here that just goes unseen or unidentified. There is high potential for other rare Larids, I reckon, review species and otherwise.

*Shorebirding in Santa Clara is simultaneously great and frustrating. We have numerous salt ponds but very limited access to tidal mudflats, despite being right on San Francisco Bay. This results in the weird scenario of me having seen 2 Little Stints in the county and just 1 Sanderling. Rockpipers stay further north in the bay, and we don't have any good grasspiper or Pluvialis spots. However, Santa Clara could easily be where California's next greenshank, redshank, Curlew Sandpiper, etc. shows up.

*Speaking of said salt ponds, I want to start biking around them...that way I could really cover some ground, see some shit, get to places I wouldn't normally be able to get to. The salt ponds cover a vast area and there is a lot of public access - I suppose that means I should get a bike. Or someone could get me vehicular access out there to do some shorebird surveys or something. Any takers? I am the #7 birder in the United States...and a biologist.

*Santa Clara has a number of species that other bay area counties lack or scarcely have, such as Swainson's Hawk, Black-chinned Hummingbird, Pileated Woodpecker, Yellow-billed Magpie, Canyon Wren (above, belting out its heartmelting song at Coyote Dam), Bell's and Black-chinned Sparrows and Lawrence's Goldfinches to name just a few. Although vagrants may be tough here, there is quite a good diversity of upland species overall.

*Alviso Marina may be one of the most reliable places for Black Rail in the entire country. After being relegated to the "heard only" list for years, I finally saw a Black Rail! I took a picture of a Black Rail! I have done the impossible! This wasn't a county bird like everything else photographed in this post, but who gives a shit? It's a BLACK RAIL.

So how have I done with the county birds this year? I started 2018 with 220 species in Santa Clara County. As of this writing, I've got 244 according to what eBird tracks. It ain't nothing to brag about, but I'm pleased with my progress. 250 is in my sights, a number which I see as evidence of established residency in Santa Clara County. And with fall migration now peaking for another month or so, it's possible I could get there before 2019, a year shaping up to be filled with mystery and intrigue. Since so much of my birding in the this year has not come up in BB&B, why don't we revisit some of these county birds?

Look at this COUNTY BIRD. It's not just any county bird, it's a Pileated Woodpecker, and this one gave the best looks I've had of one in my whole stupid life. I have no idea how long I stood there staring at it like an idiot. I couldn't believe my luck. It gave neither two shits, nor a fuck, about my presence. I stood as close to it as the intervening terrain and vegetation would allow. It was so engrossed in digging into this tree trunk that it wouldn't even look at me...probably because I looked like a total wanker just standing there with jaw agape. Photographed at Sanborn County Park.

With a bit of eBird sleuthing, I was able to figure out where to find a day-roosting Western Screech-Owl! I love it when piecing vague details from eBird comes together to coalesce into a COUNTY BIRD! This is only the second WESO I've been able to have truly leisurely looks at, and it was as invigorating as you would expect. There is something about the patterning on screech-owls that I find mesmerizing...fuck mossy oak, camo makers should be putting out screech-owl.

Willow Flycatchers pass through the bay area in appreciable numbers in fall. Rare breeders in California, I presume these birds are mostly coming from breeding grounds in British Columbia, Washington and Oregon, but perhaps they include individuals from further east as well. For most species, we really don't know shit about migration, do we? Anyhoo I am grateful for the existence of Willow Flycatchers because they are easy to identify compared to other western Empids, unless you are trying to turn one into an Alder, in which case you are fucked. This was not only a COUNTY BIRD, but a satisfying addition to the 5MR ledger as well.

Hermit Warbler was a recent COUNTY BIRD, the last holdout of the west coast warblers. The autumnal diaspora of Hermits mostly occurs in August and September...hopefully this won't be my last of the year. This one was at Ulistac Natural Area, which seems to be the premiere (publicly accessible) migrant trap in the county. Fingers crossed this won't be the last new warbler I see in Santa Clara this fall. That would suck.

One of the best birds seen in Santa Clara in 2018 was the Anderson Lake Zone-tailed Hawk. I didn't see it. In fact, I didn't even bother looking for it, and saved myself many hours of fruitlessly standing around a parking lot in the process (most birders dipped on it). Why? My best self-found bird in the county since moving here was an immature Zone-tailed Hawk last November on Laguna Road in Coyote Valley. It is the second county record in eBird, and first photographed. Here is a classic crappy photo. COUNTY BIRD! And the first I've had the pleasure of seeing north of Santa Barbara, it is a solid rarity north of there.

Whether you give a damn about getting county birds or not, I hope you all have a good September. Bay area birders, please find something like Eastern Yellow Wagtail, Gray-cheeked Thrush or Cerulean Warbler. Those would be STATE birds...

Introducing Smith's Flycatcher or Double Bear Attack At Moonglow

I was somewhere far from most other places. Modoc County, California, is the northeasternmost county in the state. It is home to just 9,000 people; for comparison, my current home county of Santa Clara has almost 2 million residents. California birders love birding Modoc, despite how far it is from where most people live in the state. Modoc offers Trumpeter Swan, Black-backed Woodpecker, Bobolink...Cordilleran Flycatcher...and Smith's Flycatcher.

Ah yes, the enigmatic Smith's Flycatcher (SMFL). Genetically, they are somewhere in between Hammond's/Dusky and Least Flycatchers...possibly the worst place for any bird to be. Amazingly, despite its close relations to these other birds, they appear more akin to an Eastern Phoebe with wingbars and longer primaries.

North of Mexico, of all Empidonax, only Buff-breasted Flycatcher has a more restricted range. Smith's breeds only in Modoc County, southeastern Oregon, and a couple of isolated mountain ranges in northwestern Nevada. No one knows where they winter, so if you want to see one, it is necessary to meet them on their breeding grounds. This mysterious species is highly sought after by birders.

That's what I was doing in Modoc County. The trip wasn't exactly going as planned...shorebirds not where they were supposed to be...lodging plans falling through...but eventually I did find the phoebeish little flycatcher in its shady coniferous haunts. What a satisfying bird! All was well.

                                                                        ***
And all was well at Moonglow Dairy, at least at first. Moonglow Dairy is a dairy farm in Moss Landing, California, on the south side of Elkhorn Slough. Moonglow is known to birders as being one of the few coastal strongholds for Tricolored Blackbirds in the state, and as a legendary vagrant trap. There are few things one can do that are more reasonable than birding Moonglow in fall, and that's what I found myself doing with a few other nerds.

I was concerned, however, about the bears. Bears had been in the area lately, and they had been aggressive. The others in my party did not seem very concerned about them, but within minutes of arriving BEARS came crashing through the brush and confronted us out in the open. It was a mother and her two half-grown cubs. However, she stayed back while the two cubs came forward and attacked myself and other birder.

Luckily, I somehow got a hold of a METAL FOLDING CHAIR, which I held out between and myself and the bear, like an old-school lion tamer. The bear pawed at it and expressed great displeasure at the chair being deployed, and quickly lost enthusiasm. After another minute of halfhearted assault the bear gave up and turned back, and the other followed suit. The whole bear family ambled off together, and we were left to bird in peace.

                                                                         ***
Of course, the events I just related to you did not actually happen. These were dreams that I had on successive nights, which led right into the weekend. The places are real, but the content, not so much. These dreams were not random though, I assure you, they undoubtedly meant something...but the only way to unlock this hidden meaning was to act on them. So what could I do? I had to bird Moonglow Dairy, I had no choice. Modoc may be far away, but Moonglow is less than an hour south of me. Luckily, birding Moonglow on a September weekend is like coffee and cigarettes...my course of action may have been predetermined, but I had no qualms about it.

Despite the warm weather and clear skies, Moonglow was very, very birdy. Lots of cooperative Tricolored Blackbirds greeted me on the way in.

Horned Larks and this fresh Western Meadowlark were along the road as well, searching for encroaching bears.

A couple Pacific-slope Flycatchers foraged in the Eucalyptus at the parking area. It soon became apparent that there were a lot of migrants around. A Black-headed Grosbeak gave a brief view, and a yellow female oriole appeared near the treetops - luckily, it began calling repeatedly, so no doubt about it being a Hooded. I considered myself fortunate - she never came down very low, so it easily could have resulted in a cringe-worthy Hooded/Orchard situation.

This Willow Flycatcher accompanied some low-foraging Yellow Warblers.

Yellow Warblers...at first I thought there were a lot of Yellow Warblers around, then it became increasingly clear that there were more Yellow Warblers present than anywhere I'd birded before. Ever. They were utilizing all the vegetated habitat around, low and high. It had the vague feeling of a fallout.

A MacGillivray's Warbler was lurking at the edge of the pond with a throng of Yellows. This species is very hard to find on the coast (it was a year bird for me); the dedicated fall birder may see more of several "eastern" species than of western birds like Cassin's Vireos and MacGillivray's Warblers.

It had been a long while since I had good looks at a Pectoral Sandpiper. This bird was very obliging.

An unearthly bellow shattered the peaceful silence, and I dared not approach any closer. Was this the rarely observed bear alarm call that I have read so much about?

No sounds were uttered from this creature, bellowed or otherwise. I determined that it was not a bear.

Elkhorn Slough, which backs up against Moonglow, is well known for its abundance of trusting sea otters. Sea otters, of course, are one of the best organisms on the face of the earth. If you find yourself in the area from out of country or out of state, make sure you make an otter detour. You won't regret it.

I went back to bird the Eucalpytus grove again - things had really quieted down, and the teeming herds of my grunts present earlier in the morning seemed to have dispersed. I was following a couple Pacific-slope Flycatchers around when another bird appeared.

At first, I was confused. This sure was a strange PSFL...it doesn't seem to be very yellow...the eye ring is quite round...the bill seems a tad short....why does it have crazy white stripes on the tertials? Ohhhhh...it's a Least Flycatcher. Least Flycatcher!

Though a far cry from a Bird Police species, Least Flycatchers are quite rare in California, and like all their bretheren, are misidentified on the regular. I stuck around for a while to look at it as much as I could. In typical fashion, at one point I had refound it at the exact moment when the Moonglow owner pulled up to chat with me...there was nothing I could do but turn my back to the bird. Persistence did pay off through, and I got quality looks before I left. As an aside, you gotta love when private landowners let birders roam freely on their vagrant-riddled property, even if you have to talk to them at inopportune times.

Aside from not being a yellow bird (the vast majority of empids we get on the coast are yellowish Pacific-slopes), one of the most striking features about this bird was how much the bright white tertial edgings stood out compared to the Pacific-slopes and Willow that were also present. This was apparent even in poor light. I never managed a good photo that showed this, but I did managed a crap photo that shows this (last photo above). Everything else looked typical for a fall Least from what I gather, though a touch of darkness at the tip of the lower mandible would have been the frosting on the flycatcher cake.

I had done it. I had come as close as possible to finding Smith's Flycatcher...this was my first self-found Least west of Texas, and I owed it all to a couple of bizarre nerddreams. In a certain sense, I had fulfilled my cosmic destiny, carried out the orders given to me on the astral plane. It turns out that most people have never fulfilled their destiny, so I'm not sure how much you can relate...but I assure you, it is accompanied by a special kind of glory. Things will never be the same. But what does it all mean? I may have to return to Modoc to find out. 

Sic Semper Tyrannus

Yellow-bellied Flycatcher is an Empid I hold, for some reason, in high regard. I first met the species in Pennsylvania back in 2009, and we have since crossed paths in Florida, Mexico, Costa Rica, and now Texas. Photographed at South Padre Island, TX.

Texas is a state rich in flycatchers...with only one exception (Gray Kingbird), every flycatcher that breeds east of Texas is found regularly in the state. And then there are Scissor-tails, and the valley species, and all the vagrants they have been blessed to receive over the years. I'm not ambitious enough to post pics of every flycatcher species I saw out there last spring...but I can do most of them.

Are flycatchers a major headache migraine? Does looking at them make you feel stupid? Do high-ranking birders with mysterious motives make false statements about how often they vocalize? Yes! But that is part of what makes them so great. You don't have to worry about them hybridizing (much) and they are a group of birds that your new birding app won't be able to identify for you for a very, very long time. And they do stuff. Good stuff.

When you get to the end of the post and are drenched in sweat, feel free to cruise over to The Powdermill Reserve (the only place I've seen Yellow-bellied Flycatcher in hand) for a nice post on more eastern flycatchers.

I'm itching to find one out here in California...most (not all) of the individuals I've seen have been pretty easy to ID, and they tend to stand out...they are yellow (er...olive and faintly yellowish) and have a call that isn't a damn "whit" note. South Padre Island, TX.

Least Flycatcher...the gray flycatcher of the east. It is the most basic Empid of the east, in terms of color and abundance. South Padre Island, TX.

Least Flycatcher, probably the same individual as above. Note the amount of darkness on the mandible (or lower mandible, as most of us say), which is atypical. I've always found the amount of paleness here to be dependably variable in many Empid species, and a field guide could potentially lead the birder astray with this character. South Padre Island, TX.

Acadian Flycatcher has a big head and big bill, a true loggerhead of the Empidonax. South Padre Island, TX.

Traill's Flycatcher (the pre-split name of Alder and Willow Flycatchers) is one of the most troubling species-pairs that eastern birders have to face. Even California birders are pained by this problem, as a handful of legit Alders have been documented in the state over the years...and guess what? We want more. South Padre Island, TX.

This is the same bird as above. Note the overall gray-brown on the upperparts that does not contrast with the throat, rendering it quite dull even by Empidonax standards. There is an eyering present, but it is extremely narrow, which is to be expected in eastern Willow Flycatchers. There doesn't appear to be any greenish coloration from this angle, aside from the inside of the folded wing; it is remarkably drab. By all accounts, this is a Willow Flycatcher.

Here is a different Traill's from South Padre Island. This bird is a bit greener and more contrasty in the throat than the above individual, has a more pronounced eyering and seemingly has a shorter bill. It actually looks considerably different than the above bird. I'm going with Alder Flycatcher on this one. Of course, empids can look quite a bit different in fall, so there's only so far one can go with some of these field marks without hearing a vocalization...but it never hurts to try. South Padre Island, TX.

Eastern Wood-Pewee has the distinction of being one of the most misidentified flycatchers in the U.S., despite being one of the most abundant. Learn the pewees, and then you will love them. Until then, you will not have a healthy relationship. South Padre Island, TX.

Couch's Kingbird. This is a typical brightly-colored bird with a smallish bill. Atypical is how the tail appears completely unnotched. Willacy County, TX.

Couch's Kingbird. There is variation in bill structure in this species, and you can see that this bird has a heavier bill than the above individual, being especially deep toward the base. I reckon Tropical Kingbirds have a more consistent bill length, and still appear longer-billed (and not so big at the base) than this individual. Sabal Palm Sanctuary, Brownsville, TX.

Eastern Kingbird, a true feel-good flycatcher. Everyone can love an Eastern Kingbird. South Padre Island, TX.

Brown-crested Flycatcher. This is cooperi, the subspecies found in Texas, and is less beefy than the magister that reside in Arizona. Note the unimpressive size of the bill. Hidalgo County, TX.

Great Crested Flycatcher. God, look at the tapering of the white border of the first tertial feather! That's what I'm fucking talking about. What I'm not talking about is why Great Crested Flycatcher and Brown-crested Flycatcher have more structural differences in the grammar of their names than the birds do in reality. South Padre Island, TX.

The Death Of The Mystery Bird

In the age of the internets, birders can communicate and share photographs like never before, which along with digital photography has lead to a dramatic jump in the prevalence of "mystery birds" over the past several years. To label a bird as a mystery bird, of course, is simply just a way of saying you are unable to identify a particular bird. Nowadays, listservs, forums and facebook groups are awash in these things. I do like weighing in on these anonymous birds from time to time, despite the plethora of horrible photographs to wade through. The most infamous realm of the Mystery Bird is the ID-FRONTIERS listserv, which consists of birders willing to slit throats over such fascinating issues as the amount of expected wear on the lesser coverts of a molt-retarded 3rd-cycle Herring X Glaucous-winged Gull hybrid in July (that occurred out of normal range, but not in a completely questionable location)...which is all well and good of course, but I don't always have the stomach for such in-depth and brain-numbing semantics. That's more of The Great Ornithologist Felonious Jive's thing.

Since I am, as you know, our great nation's Number 7 birder, it's not difficult to weigh in on the mystery birds that surface here and there throughout the internets. It's fun to debate birds, and gives everyone a chance to learn something. BB&B is very pro-birducation of course, so I do my best to keep it real. I do admit to being wrong one (1) time of late, when an outranking birder whose name rhymes with "Benn Baufman" correctly nailed down a sparrow that I could not. All hail!

Over the past few years of checking out these Birds of Mystery, certain patterns begin to emerge that I think are representative of the challenges that birders throughout the U.S. and Canada often face. So, now, I give to you, The Final Guide to Identifying Mystery Birds. Chances are, if you've only been addicted to birds for a few years or less, the fuzzy, blurry, anonymous bird you have a picture of will be pictured or mentioned somewhere in this post. You are welcome.

The bird groups that people seem to struggle with the most are flycatchers, sparrows, buntings, warblers and shorebirds. Surely seabirds and gulls have surely crippled many a birder as well (I'm still working on my degree in International Storm-petrel Studies), but I can't argue with Pure Statistics.

And now...your mystery birds are revealed.

Is your mystery bird yellow? Is it a warbler? Good chance it's a Yellow Warbler. They don't look like this in fall, so don't expect them to. Des Lacs National Wildlife Refuge, ND.

See a weird sparrow? Well...is it a Song Sparrow? Song Sparrows are one of the champion sparrows for confusing people. Like Yellow Warblers, they are more variable than people think, with a staggering 24 subspecies in the U.S. That is more than any other North American bird! Amazingly, 11 of these breed in California, with 4 other subspecies occurring in winter. Point Reyes, CA.

Western Wood-Pewee. People are terrible at identifying flycatchers (I don't blame them), in particular both species of wood-pewee. Lack of eyering and long primaries make it easy though, and the dull wingbars help as well. Advanced birders struggle with vagrant pewees (a Western in Eastern Wood-Pewee range, and vice versa); for silent birds, I see no end in sight to this problem. Fort Rosecrans National Cemetery, San Diego, CA.

Willow Flycatchers are equally notorious for confusing birders, since they resemble both wood-pewees and Alder Flycatchers, and can also be confused for other Empidonax. Some birders are under the false impression that Willows never have eyerings (which they can, particularly in the east), which makes it even messier. But lets face it, this genus stems from its own special circle of Birder Hell. Port Hueneme, CA.

Common Terns seem to be the Most Mysterious Tern. Probably because they can turn up anywhere on the continent, and that they are frustratingly similar to Forster's, Arctic and Roseate Terns. Ormond Beach, Port Hueneme, CA.

Looking at people's "mystery shorebirds", Least Sandpiper wins the award for our Most Mysterious Sandpiper, despite the fact it is our only peep with yellow legs. Being tiny, their name is a good clue as well. Just the other day a local birder reported 4 Sharp-tailed Sandpipers at a marsh...can you guess what they were? San Diego River, San Diego, CA.

Tennessee Warbler. In spring they look like vireos, in fall they can still look like vireos, as well as a number of other warbler species. An understandably confusing bird for fledgling birders. Lostwood National Wildlife Refuge, ND.

Ruby-throated Hummingbird. Despite being practically the only "eastern" hummingbird, they somehow continue to confuse birders within their normal range. A great example is one in Maryland that was recently reported as a Magnificent Hummingbird. We know this to be the case because the photos show a Ruby-throated Hummingbird. Sadly, a number of birders attempted to chase this staggering rarity in vain. Chavarrillo, Veracruz, Mexico.

Savannah Sparrow ("Belding's" subspecies pictured). Savannah Sparrows are hard for people to come to terms with, but with a massive range and a number of different and probably incorrectly described subspecies, this is understandable. Streaky sparrow give you brain freeze? Think about these duders, whether in a coastal marsh or open grasslands...yellow lores are a giveaway. Imperial Beach, CA.

Chipping Sparrows. People recognize them in their summer duds, but not as a grotesque juvenile or basic-plumaged bird. Juvenile Spizella can be nightmarish to identify for many a birder, but Chipping is (arguably) the easiest to identify in this streaky state. Point Reyes, CA.

Common Yellowthroat, by my calculations, is the Most Common Mystery Bird Of All Time. Female, juvenile, and hatch year birds of both sexes get misidentified for all sorts of other warblers. And yes, despite the tens of thousands I have seen by now, I still don't have a good photo of one...how embarrassing! Tijuana River Valley, CA.

Are none of these species your mystery bird? Are you sure? Well, it seems that Magnolia Warbler, Indigo Bunting, Swainson's Thrush, Western and Baird's Sandpipers, juvenile Verdin and Brown-headed Cowbird all turn up frequently as mystery birds. You should consider them in your quest for The Final ID.

I should remind birders to use their field guides to their fullest...i.e. don't just look at the pictures, read the text and range maps. It's good stuff, I swear. That makes all of this a lot easier.

There you go. Case closed. No more mystery birds, ever again. Rejoice, and bask in wisdom and knowledge!
